| Abstract: | The rice seeds of Longdao No.5 were selected as experimental materials.The seeds of Longdao No.5 were exposed by femtosecond laser at the wavelength of 800 nm,spot radius of 2 mm,power 650 mW and frequency of 1 000 Hz for 3 s,5 s,7 s,9 s,11 s and 13 s,separately.The effect of femtosecond laser irradiation on rice seed germination and seedling growth were studied.The results showed that the germination and the seedling growth of rice were stimulated by exposing the rice seeds with femtosecond laser.3～9 s femtosecond laser irradiation increased the rice germinating viability and germination rate.The inhibition of sprouting happened with the 11～13 s femtosecond laser irradiation.The height of the rice plant was increased by exposing the rice seeds especially when the seeds were exposed for 11 s and 13 s.The chlorophyll content,the POD activity increased and the SOD activity decreased after the irradiation treatment. |
